I did an offer and it worked fabulously. My husband, who also has a Gaia account, tried to do the offer as well from his own computer but it wouldn't let him. Was it because we are using the same internet connection?
A couple years ago I believe they did, I was denied Cash after doing an offer on a public computer. I even contacted them, they basically said "tough cookies" and did nothing to help. Can't say for sure about now though.
